More about the product
The Pioneer GM-DX874 is a high-performance 4-channel car amplifier designed to deliver clean, powerful sound across front and rear speaker setups. Finished in a sleek black chassis with brushed aluminium accents and gold-plated terminals, it combines premium aesthetics with solid build quality. This model is part of Pioneer’s GM-DX series, offering enhanced audio clarity and efficient power handling through Class-D technology.
The GM-DX874 delivers a maximum power output of 1200W. At 4 ohms, it provides 100W x 4 RMS, while at 2 ohms it pushes 150W x 4 RMS. It also supports bridged operation at 300W x 2 RMS, allowing users to power larger speakers or subwoofers if needed. The amplifier includes variable high-pass and low-pass filters, giving users control over frequency response and helping to fine-tune sound quality based on speaker type and placement.
Installation is simplified with speaker-level inputs, making it compatible with factory head units without needing extra adapters. The compact design allows for flexible mounting options, even in vehicles with limited space. The amplifier also features a turn-on selector and signal sensing for automatic power-up when audio is detected.
The GM-DX874 does not include wireless connectivity or DSP tuning, focusing instead on reliable wired performance and straightforward controls. It’s built for users who want to upgrade their sound system with better clarity and volume without adding complexity.
With its combination of efficient Class-D power, flexible configuration options, and premium finish, the Pioneer GM-DX874 suits a wide range of vehicles and audio setups.
